Frequently asked questions
Straight answers about shopping, delivery in South Africa, and food supplements—without medical promises.
Who is PureBlink for?
Adults who choose to buy food supplements online and use them only as the pack directs. We do not sell medicines or give medical advice.
Can I use supplements when I work at a screen a lot?
Only according to the label and your own situation. We don’t claim that any product prevents or relieves eye strain, dryness, or fatigue—that would be a health outcome.
Is it a medicine?
No. Our range is food supplements where stated on pack—not medicines and not substitutes for professional diagnosis or treatment.
How often should I take them?
Follow the manufacturer’s directions on the pack. If you are unsure, or you feel unwell, stop and speak to a qualified professional.
Is delivery available across South Africa?
Yes. We dispatch nationwide via trusted couriers. Timeframes vary by region—see our Shipping Policy for estimates.
What makes each formula different?
Each listing matches a real pack photo: e.g. Oculax (B2 & zinc capsules), Vizonal & Dioptik (10 caps), Vizonic Premium (tablets), Zenith Labs Vision 20, Ophtalmica Nova (Geberich), OptiPills. All are food supplements, not medicines.
Which formula is best for night use?
Choose based on pack format (capsules vs tablets) and your routine. For evening-focused options, compare labels—or contact us. Food supplements only; not medicines.
Are bundles available?
Yes—choose duo packs, triple stacks, and larger household options where shown. Savings are in ZAR on the shop page (for example, Save R150 on selected bundles).
Can I wear contact lenses?
Contact lenses need professional fitting and care rules. Our products are oral supplements, not lens solutions—follow your practitioner’s advice.
What payment methods do you accept?
We accept major cards and popular South African payment methods at checkout (final options are shown when you purchase).
How do returns work?
See our Returns Policy for eligibility, timeframes, and how to contact support with your order number.
